摘　　要：传统路由协议在移动自组网中通常具有较多的多点继电器(MPR)重计算或路由表重计算过程,导致表现不佳,提出一种在移动自组网中所有节点对之间建立稳定且可持续路径的机制。首先分析了节点稳定性和节点保真度两个概念;然后将这两个概念整合到优化的链路状态路由(OLSR)协议中;最后在OLSR协议中使用一种稳定性函数作为主路径选择标准来选取稳定且可持续的多点继电器节点和拓扑。提出的机制显著减少了MPR的重计算和路由表重计算过程,且确保了其他Qo S(服务质量)指标。仿真结果表明了该机制的有效性,同时支持对该机制进行扩展,从而确保其他Qo S需求。Classic routing protocol usually has heavy recomputation of multipoint relay （MPR） or routing table in mobile Ad hoc networks （MANET） , for which this paper proposed a new mechanism to establish stable and sustainable paths between all pairs of nodes in a mobile Ad hoc network. Firstly, it analyzed the concepts of stability of node and fidelity of node. Then the two concepts were integrated to the optimized link state routing （OLSR） protocol. Finally, it used a stability function as the main path selection criterion in the OLSR protocol to elect stable and sustainable MPR nodes and topology. The proposed mechanism significantly minimized the recalculation of MPR and the routing tables recalculation process. Moreover, it guaran- teed other QoS （ quality of service） metrics. The simulation results show the effectiveness of this mechanism and encourage further investigations to extend it in order to guarantee other QoS requirements.
